Question

I dont know how to do this??

Answer 1

21

Explanation:

the formula is:

[(base1+base2)/2]*height
[(9+5)/2]*3

21

Answer 2

21 m²

Explanation:

Area of a trapezoid is given by the formula:

A = (a+b)/2×h

(where h is the vertcial height, and a and b are the parallel lines)

Substituting values given gives us:

A = (5+9)/2×3

A = 14/2×3

A = 7×3

A = 21

Units will be m² as this is area.
